高一英语学习方法：语法it的用法

【摘要】高中学生在学习中或多或少有一些困惑，精品学习网的编辑为大家总结了高一英语学习方法：语法it的用法，各位考生可以参考。

“It” 用法及其句型和固定搭配，是英语语法的重点、难点，又是近几年考试的热点，因此在复习中应给予足够的重视。

现将it用法归纳如下：

1.It is+被强调部分+that

该句型是强调句型，将被强调的放在前面，其他部分置于之后，强调的主语如果是人，可以用来替换，如果把这种句型结构划掉后，应该是一个完整无缺的句子，这也是判断强调句型与其他从句的方法。

It was they that (who) cleaned the classroom yesterday. It was in the street that I met her father.

It was with great joy ___he received the news that his lost daughter had been found. (2004 福建)

A. because B. which C. since D. that (D)

2. It is not until +被强调的部分+ that

该句型译成汉语“直到……才”，可以说是的强调形式。It was not until she took off her dark glasses that I realized she was a film star. =Not until she took off her dark glasses did I realize she was a film star. =I didn’t realize she was a famous film star until she took off her dark glasses.

It was ___back home after the experiment. (2004 湖北)

A. not until midnight did he go

B. until midnight that he didn’t go

C. not until midnight that he went

D. until midnight when he didn’t go (C)

3. It is clear (obvious, true, possible, certain) that….

该句型中it是形式主语，真正的主语是that引导的主语从句，常译为“清楚(显然、真的、肯定)”是主语从句最常见的结构。

It is very clear that he’s round and tall like a tree.

=That he’s round and tall like a tree is very clear.

4. It is important (necessary, right, strange, natural…) that…

该句型和上一句同属一个句型。由于主句中的形容词不同，that后的从句中要用虚拟语气(should+动词原形)should 可以省去。建议记住该句型中的形容词。

It is important that we (should) learn English well.

It is necessary that he (should) remember these words.

5. It is said (reported, learned…) that…

该句型中的it 仍是形式主语，真正的主语是that 引导的主语从句。该结构常译为“据说(据报道，据悉……)

It is said that he has come to Beijing.

It is reported that another earth satellite has been put into orbit.

6. It is suggested (ordered…) that…
